Insight summary

Mercedes-Benz Cla is an uncommon model in this snapshot, with 60,155 represented vehicles and 0.14% of the active UK pool tracked by AutoRank. For the last 5 years, it has a pass rate of 83.6% from 328,275 MOT tests, with a reliability score of 53. The current pool shows an average of 66,444 miles and an average age of 7.5 years, while mature-fleet mileage is estimated at 92,277 miles. Petrol leads the fuel split, followed by diesel, and the most frequent defect themes are windscreen damage, tyre condition and engine warning light. The practical read is that the Mercedes-Benz Cla looks like a solid used-car baseline rather than a rare find, with age, mileage and common wear items doing most of the explaining.
